While we're on the Site 2 Site subject, I have some trouble with the
otherwise wonderful utility TaskMaster.

Has anybody found the perfect packet size for UDP and NCP
communications? It sems that UDP mode is almost impossible to run for
more than 5-10 megabytes without breaking out with a communications
error, no matter what the packet length is.

NCP works, of course, but what would be the optimal packet size?
I use TaskMaster to Sync from a slave to a master server, wich takes
care of backup.

All traffic stays in the tunnel.

What would be optimal packet size for "tunnel only" traffic?
